Gastrointestinal and weight loss issues?
Hello Dr.
Tsai,
Question 1: I have read online that poor absorption in the small intestine is usually associated with thin individuals, but I am overweight.
Why is this the case?
Question 2: I can understand that undigested corn appears in stool, but I also notice that leafy greens like sweet potato leaves are similarly undigested.
Is this abnormal? Although this has been an issue for me since childhood, it has recently worsened over the past month, as I have been experiencing increased diarrhea and abdominal cramps.
I have been seriously trying to lose weight this past month, drinking 4600cc of water daily, and aside from boiled leafy vegetables for dinner, my diet is otherwise normal.
Could this be related?

Hello: 1) How to know if your small intestine absorption is poor? 2) Even with fiber, if it is not chewed properly, it can be excreted in its original form.
3) You can consult a gastroenterologist for diagnosis to see if there are any issues.

Understanding gastrointestinal issues and their potential impact on weight loss can be complex, especially when considering various factors such as diet, digestion, and underlying health conditions. Let's address your questions one by one.
Question 1: Why can I be overweight if I have poor absorption in my small intestine?
It’s a common misconception that poor absorption in the small intestine always leads to weight loss. While malabsorption can result in weight loss for some individuals, it does not apply universally. Factors such as caloric intake, metabolic rate, and the body's ability to store fat play significant roles in determining body weight. If you consume more calories than your body burns, you can still gain weight, even if your body is not absorbing nutrients efficiently. Additionally, certain conditions like insulin resistance or hormonal imbalances can lead to weight gain despite malabsorption issues. Therefore, it’s essential to consider a comprehensive evaluation of your dietary habits, metabolic health, and any potential gastrointestinal disorders.
Question 2: Is it normal for undigested food, like sweet potato leaves, to appear in my stool?
Seeing undigested food in your stool can be concerning, but it is not always indicative of a serious problem. Some foods, particularly those high in fiber, can pass through the digestive system without being fully broken down. Sweet potato leaves and other leafy greens are rich in fiber, which can sometimes remain intact during digestion. However, if you notice an increase in undigested food particles, especially alongside symptoms like diarrhea and abdominal pain, it may suggest that your digestive system is struggling to process certain foods. This could be due to a variety of factors, including insufficient digestive enzymes, changes in gut flora, or underlying gastrointestinal conditions.
Regarding your recent symptoms of increased diarrhea and abdominal cramping:
The increase in bowel movements and abdominal pain could be related to several factors, including dietary changes, stress, or an underlying gastrointestinal disorder such as irritable bowel syndrome (IBS) or inflammatory bowel disease (IBD). Since you mentioned that you have been diligently reducing your caloric intake and increasing your water consumption, it’s possible that these changes are affecting your digestive system. A high intake of water combined with a significant reduction in food intake can lead to changes in bowel habits, including diarrhea.
Recommendations for Improvement:
1. Dietary Adjustments: Focus on a balanced diet that includes a variety of foods. While leafy greens are healthy, ensure you are also consuming adequate proteins, healthy fats, and complex carbohydrates. Avoid overly restrictive diets, as they can lead to nutrient deficiencies and digestive issues.
2. Gradual Changes: If you are making significant changes to your diet, do so gradually. Sudden changes can shock your digestive system and lead to symptoms like cramping and diarrhea.
3. Hydration: While staying hydrated is essential, ensure that your water intake is balanced with your food intake. Drinking excessive amounts of water without sufficient food can lead to electrolyte imbalances.
4. Monitor Symptoms: Keep a food diary to track what you eat and any symptoms that arise. This can help identify potential food intolerances or triggers.
5. Consult a Healthcare Provider: Given your symptoms, it would be wise to consult a gastroenterologist or a registered dietitian. They can perform necessary tests to rule out conditions like IBS, IBD, or malabsorption syndromes and provide tailored dietary advice.
In conclusion, gastrointestinal issues can significantly impact weight and overall health. Understanding the underlying causes and making informed dietary choices are crucial steps toward improving your symptoms and achieving a healthier weight.
